Earlier this week Microsoft announced App-V 5.0 Beta. You can download it from Microsoft Connect, try and investigate what has changed. While reading some articles it seems to be rewritten from scratch, I guess the name Softgrid is now history.
A short summary:
- A new format with the extension .APPV
- The format SFT is gone.
- No Q drive anymore
- No more OSD files
Read the Release Notes carefully because there are known limitations.
App-V 5.0 Beta components (Client, Sequencer and Server) require both .Net 3.5 and .Net 4.0.
Sequencing Office 2010 is not supported in the Beta release.
The App-V Sequencer and Client require the latest windows updates as they contain updates critical to creating correctly formatted virtual application packages. (i.e KB2533623).
This information is found in the Microsoft Application Virtualization (App-V) 5.0 Beta Adminstrator’s Guide and the Release Notes.
Windows XP and Windows Vista not supported as the sequencer.

Posted by Martin This article describes how to configure Application Pre-launch in XenApp version 6.5.
Requirements
- Citrix Receiver 3.0 for Windows
- Online Plugin 13.0
To configure Application Pre-Launch in XenApp 6.5, complete the following procedure:
- Select an application for pre-launch from the AppCenter.
- Right-click the application and select Other tasks.
- Create a pre-launch application.
- After you complete it, a new pre-launch application is added to the application list with an icon followed by an application name, as shown in the following screen shot.
Note: Pre-launch is available only for the application’s configured users.
- On the client device, verify the setting of the following registry key(Default Installation Values):
32bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Prelaunch
64bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Prelaunch
- Close the Receiver and then re-open it.
Note: Do not start any applications.
- In AppCenter that the application is set for prelaunch.
- The following screen shot displays a calculator that is a prelaunch application and ready to use. The application is now ready to start.
- It is a best practice to also set the folowing policies:
Pre-launch Terminate Timer Interval
Maximum amount of time before the pre-launch application exits (60 minutes by default)
Pre-launch Disconnect Timer Interval
Amount of time before the pre-launch application disconnects the session (60 minutes by default)

Posted by Fred Symptoms
The Adobe Acrobat Reader application stops to respond. This issue is observed on a Server console, RDP, and ICA Connections versions 9.1, 9.5, and 10.1.0.
This issue exists only on a 64-bit server. The Adobe Acrobat Reader application that is installed on 32-bit server functions as expected.
Cause
Several Adobe Acrobat Reader .dll files have conflict with Citrix Memory Management feature.
Resolution
1. To resolve the preceding issue, complete the following procedure:
- Exclude the following files from Memory Optimization that has stopped Adobe Acrobat Reader on the 64-bit Windows 2003 Servers:
Note: Ensure that you enable the Use farm settings option.
- C:\Program Files (x86)\adobe\reader 9.0\reader\AdobeXMP.dll
- C:\Program Files (x86)\adobe\reader 9.0\reader\BIBUtils.dll
- C:\Program Files (x86)\adobe\reader 9.0\reader\logsession.dll
- C:\Program Files (x86)\adobe\reader 9.0\reader\LogTransport2.dll
- C:\Program Files (x86)\adobe\reader 9.0\reader\sqlite.dll
NOTE: Try to include the C:\Program Files (x86)\adobe\reader 9.0\reader\AcroRd32.exe file, even though this file is not listed by ADSCleaner Tool.Reset the CPU/Memory Optimization of the affected XenApp servers to the farm default settings.
2. Reset the CPU/Memory Optimization of the affected XenApp servers to the farm default settings.
3. Clean the streams of the affected XenApp servers with ADSCleaner tool (CTX108542).

Posted by Martin When I upgraded my Citrix Receiver 3.0 to 3.1, I ran into the fact that a https address instead of a http must be configured in the preferences.
There is a way to allow configuring http instead of https. This can be done by adding/changing the following registry keys:
HKLM\SOFTWARE\Citrix\AuthManager (on a 32-bit machine) or
HKLM\SOFTWARE\Wow6432Node\Citrix\AuthManager (on a 64-bit machine)
Under AuthManager create a new String Value (REG_SZ) with the name “ConnectionSecurityMode” and the Data “Any”
AND
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Dazzle (on a 32-bit machine) or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle (on a 64-bit machine)
Under “Dazzle” modify the existing data of “AllowAddStore” to be “A”.

Posted by Martin Last friday I was at the first DUCUG (Dutch Citrix User Group) event in Amsterdam, which was a great, well organized and interesting day. Jim Moyle had a great and presentation about Windows 7 and IOPS. A surprising outcome which makes you start thinking about designing environments (especially VDI).

Posted by Fred Today I have been reading a useful article in the Citrix Knowledge Center about troubleshooting installation or removal issues with Citrix XenApp, CTX132117.
I guess it can also be consulted for troubleshooting installation or removal issues with other software.
When trying to install or remove any XenApp Software (including hotfixes and rollup packs), a 1603 Windows error message is displayed.
The following are the possible error messages that are displayed when trying to install or remove any XenApp Software:
Error 1603: A fatal error occurred during installation
